A few species of the same can be found in Indo-Pacific.They anchor themselves on the depths of the ocean floor to mud or sand, as opposed to other coral that Is attached to hard substrates or coral reefs. Do I need to feed my sea fan? This SunGrow sea fan has been dried and does not require feeding. Other species of gorgonians/ sea fans do require feeding with various sea foods such as shrimps, clams, squid etc. Simply place this sea fan into your aquarium to enhance the décor and create an amazing Aquascape. Is this safe for my aquarium/terrarium? The branches of this dramatic piece of coral have been coated especially for aquarium/terrarium use. This will ensure that the coral will not affect the PH levels of the water in your tank. When you get it, give it a rinse once and place it in the tank. How do I attach this to my substrate? The base of this sea willow is brown in color, and is usually attached to a small piece of rock, which you can place on the floor of your tank. You can also bury the base into the sandy substrate of your aquarium. Will the sea fan decay or become coated in algae? You can submerg...

  • Carib Sea ACS00020 Aragonite Reef Sand for Aquarium, 15-Pound

    Don’t settle for an ordinary gravel. Natural dramatic colors and textures combined with pH support characterize our Coraline and Seafloor products. These are coarser materials suitable for most under gravel filtration and fish systems or as an accent for finer sands anywhere where elevated pH values are desirable. Consider the Coraline products in brackish or Cichlid aquariums (Central American or African). Seafloor Puka Shell substrates are great additions to fine sands in reef tanks where animals make their homes by burrowing in the substrate. Jaw fish, blennies and burrowing crustaceans will especially appreciate the extra “construction material.” Our substrates are purposely engineered and free of impurities such as ash, metals, pesticides, and silica; which allows you to create a safe and beautiful environment for your fish and invertebrates. Precision grading makes system design a breeze! No matter what type of system you are setting up, we have the substrate that’s perfect for the filtration method and habitat you are creating.

  • Onyx Sand, 7 kg / 15.4 lbs

    Onyx Sand is a specially fracted, stable porous gravel for the natural planted aquarium. Being carbonate rich, Onyx Sand provides an advantage to any plants able to utilize bicarbonates. Although ideally suited to planted aquaria, it may be used in any aquarium environment. Onyx Sand is most effective when used alone as an integral substrate bed, but it may be mixed with other gravels. Gravel modifiers such as laterite are not necessary. Onyx Sand is not chemically coated or treated but does have a slight buffering capacity that may raise pH by 0.1 - 0.5 pH units (depending on source water characteristics).

  • Brightwell Aquatics ABAKSUB1400 Kora Lagoon Substrate Filter Media for Aquarium, 3-Pound

    A blend of high-purity aragonite particulate grades to simulate the natural substrate particle profile of tropical reef lagoons. Multiple particulate grades encourage biochemical reactions (e.g. nitrification and denitrification) within the sediment to facilitate continuous release of constituent ions (calcium, carbonate, strontium, magnesium, potassium, and sixty minor and trace elements), encouraging the growth of reef-building organisms and helping stabilize ph. Over 39% calcium and 57% carbonate by dry weight. Applications include refugia, sea grass and macroalgae bed systems, mangrove systems, and other methods of filtration employing substrate to facilitate natural reduction of organic and nitrogenous waste, and reef aquaria of all sizes (notably nano-reef systems). Formulated by a marine scientist.
